Request #73066: mb_at and mb_codepoint_at

[masakielastic]

This pull request suggests mb_at and mb_codepoint_at.

string mb_at ( string $string , int $offset [, string $encoding = mb_internal_encoding() ] )
int mb_codepoint_at ( string $string , int $offset [, string $encoding = mb_internal_encoding() ] )

The one of usage of these functions is to iterate over all the chars in string.

$str = "Cat!\u{1f431}";

$gen = (function($str) {
    for ($i = 0, $len = mb_strlen($str); $i < $len; ++$i) {
        yield mb_at($str, $i);
    }
})($str);

foreach ($gen as $char) {
    echo $char, PHP_EOL;
}

AIUI, these functions could easily be implemented in userland – do we really need to add them to mbstring?

@masakielastic can we get some kind of response to the concern raised above please ?

Having waited more than a month for feedback and activity on this PR, it would seem abandoned, so I'm closing it.
